Y., ASSIGNORS, BY DIRECT AND MESNE ASSIGNMENTS, '.lO SAID LYDIA B. KOCH PAPER CONTAINER Application menne-amber 19, 1929. serial No. 415,2os.

Our invention relates to improvements in paper containers of the truncated cone type and the object of the invention is to devise fa paper container of this type which is self contained and made entirely of paper and in which the cover or closure is integral with the main body of the container and is locked in the closed position.

Our invention consists of a circular bottom,

a body and closure integrally formed from a blank and preferably Wound upon itself to form a double wall having its edges overlapping, the bottom of the wall being connected lto the bottom proper by a suitable interlocking .rim and the body being flattened gradually from bottom to top to a to edge over which the integrally formed c osure folds and locks as hereinafter more particularly described.

Figure 1 is a side view of the container with the form of the closure shown in dotted lines and the closureon one side in full lines.

Figure 2 is a side view of the container from the opposite side.

Figure 3 is a vertical section through the container with the closure folded into the closed position.

Figure .4 is a detail of the blank from Which the body and closure is formed.

Figure 5 is a plan View, and

Figure 6 is a detail of the closure.

In the drawing like vcharacters of reference indicate corresponding parts.

1 is the blank of lpaper 0f arc-shape form with substantially curved top` and bottom edges and straight ends. 1' is an lupward extension of a blank provided with Wings 12 having the notches 13. The extension 1' is designed to be folded on the perforated line 2 and also 0n the perforated lines 3, 3.

4 is the bottom made of paper in circular form With depending flanges 4 which interlock when the container is formed up with flanges formed at the bottom edge ofthe blank 1 to form a reinforcing rim at the bottom of the container. This rim does not form part of our present invention and we therefore do not particularly describe it. 50 In vforming up the main body of the conble wall as'indicated in Figs. 3 and 6, the

outer edge overlapping the inner edge as indicated in the latter figure, and it is the bottom edge of this double wall which forms With the flange at the bottom the reinforced bottom rim.

The container, it will be noticed, is substantially the same width from top to bottom looking at o'ne diameter incross-sectional plari but is, looking at the diameter at right angles to thevabove diameter, tapered from top to bottom to a pointin vertical section, but terminates in a straight edge as indicated in Figs. 1 and 2. .In short, the container is of 'a flattened truncated cone form, as will clearly appear in reference to Figs,

p 1, 2 and 3, and the plan shown in Fig; 5,.

The extension 1 `:is folded over on' thev dotted line 2 and over the strai ht edge of the flattened top as indicated in Figs 1 and 3. The Wings 12 are folded' laterally on the dotted' lines 3 onto the opposite flattened side where they may be connected together by an suitable fastening such as the coacting `sl1ts 13 formed in the wings 12, see Figs. 2 and 4.

Such a, container as we have described is a unitary one as far as the main body and closure is concerned and is suitable for various commodities particularly where it 1s not necessary to have such commodities hermetically sealed. l

It will be understood that the form of the container and its closure maybe changed to some extent .without departing from the spirit of the invention and yeome within the scope of'the claims.

Whatwe claim as our invention is:

1. A container comprising a suitable bottom, a body connected thereto by a suitable rim and of a flattened 'truncated form, terminating at the top in straight opposing edges, the centreof oneliattened side having an extension designed to be folded over the opposite edge of the opposing flattened side and means forming part of the extension for holding Ait in the turned down position.

2. A container comprising a suitable bot- -1 rim and of aflattened truncated form, terminating at the top in straight opposing edges, the centre of one flattened side having an extension designed to be folded over the opposite edge of the opposing flattened side, and lateral extendin Wings designed to be folded on the opposlte side of the vcontainer to the extension and means for holding them in the folded position.
